I won't give you my opinion on which to do (since I already have) but the requirement for having a doctorate to be a NP after 2015 is only a recommendation by the American Association of Colleges of Nurses not a hard and fast rule. Few schools even offer a DNP right now. I wouldn't make a decision based on what you think you are going to do several degrees from now, think of what you want to be doing in the next few years.
